Earlier this year, Akamai mitigated the largest DDoS attack in its history, fueled by a new reflector, memcached. The attack targeted one of our software clients and broke through the 1 Tbps threshold for the first time. Memcached was developed to act as a distributed memory caching system. Since the protocol uses UDP, an insecure protocol, and carries the potential for tremendous amplification, it has the key traits of a
Why do we need a Knowledge Base system Let me start with an obvious statement: the Internet generates a lot of data. Every day we, Akamai's security research teams, see billions of DNS queries, millions of domains, and who knows how many IP addresses. This is an exciting thing, especially if you're a data scientist. In the past year, we have taken on a "simple task": to map the "dark
Ryan Barnett, Principal Security Researcher, Akamai Elad Shuster, Senior Security Researcher, Akamai During its research into Credential Abuse attack campaigns, Akamai's threat research team conducted an analysis of web logins to gain insights into how widespread the adoption of API-based logins is and whether or not this trend also affects attackers and attack campaigns. It will come as no surprise that API-based logins are highly targeted by credential abuse attackers
Universal Plug and Play (UPnP) is a widely used protocol with a decade-long history of flawed implementations across a wide range of consumer devices. In this paper, we will cover how these aws are still present on devices, how these vulnerabilities are actively being abused, and how a feature/vulnerability set that seems to be mostly forgotten could lead to continued problems in the future with DDoS, account takeover, and malware
Ryan Barnett, Principal Security Researcher, Akamai Elad Shuster, Senior Security Researcher, Akamai API Overview Application Programming Interfaces (API) are a software design approach which enables software and system developers to integrate with other systems based on a defined set of communication methods. APIs serve as software building blocks and allow for software reuse - essentially allowing fast development of new systems based on existing capabilities.
Overview Credential abuse (CA) is a trend that is here to stay. It affects almost every one of us. There are attackers trying to break into every online account and the vast majority of these attacks are happening silently in the background. In the past, credential abuse tools were written and distributed in closed forums and among air-gapped societies. Now, they are widely available; there is a highly active market
Over the past week, memcached reflection attacks have taken the DDoS scene by storm. With several attacks hitting organizations across many industries, including a record breaking 1.3Tbps attack against an Akamai customer. Akamai has observed a new trend in extortion attempts using memcached payloads to deliver the message.
At 17:28 GMT, February 28th, Akamai experienced a 1.3 Tbps DDoS attack against one of our customers, a software development company, driven by memcached reflection. This attack was the largest attack seen to date by Akamai, more than twice the size of the September, 2016 attacks that announced the Mirai botnet and possibly the largest DDoS attack publicly disclosed. Because of memcached reflection capabilities, it is highly likely that this
Akamai is aware of a new DDoS reflection attack vector: UDP-based memcached traffic. Memcached is a tool meant to cache data and reduce strain on heavier data stores, like disk or databases. The protocol allows the server to be queried for information about key value stores and is only intended to be used on systems that are not exposed to the Internet. There is no authentication required with memcached. When
